Apple Watch Ultra is Apple’s higher-end smartwatch line, built around sports and outdoor use as well as everyday smartwatch and health features. The latest generation documented in Apple’s specifications is Apple Watch Ultra 3, introduced in 2025.
What is Apple Watch Ultra?
Apple Watch Ultra is a smartwatch made by Apple with a larger, rugged design and equipment aimed at sports and adventure. Apple positions it as a sports watch, adventure watch, smartwatch, and health companion; that is the company’s description, not an independent performance assessment. Apple’s Ultra 3 announcement describes its sports, fitness, health, connectivity, and safety features.
The product line has three generations in the official specifications reviewed here: the original Apple Watch Ultra (2022), Apple Watch Ultra 2 (2024), and Apple Watch Ultra 3 (2025). Apple Watch Ultra 3 technical specifications, Apple Watch Ultra 2 technical specifications, and original Apple Watch Ultra technical specifications identify their respective introduction years and chips.
What does Apple Watch Ultra 3 include?
Case, controls, and display
Apple lists Ultra 3 with a 49 mm Grade 5 titanium case in natural or black, 64 GB capacity, and an S10 chip. It has a customizable Action button and a built-in siren.

These are Apple’s stated specifications, not independent measurements. Apple Watch Ultra 3 technical specifications

Health and fitness features

Battery estimates
Apple estimated up to 42 hours of typical use and up to 72 hours in Low Power Mode for Ultra 3 in its September 9, 2025 announcement. The Low Power Mode estimate depends on Apple’s stated usage assumptions, and both figures are company estimates rather than independent test results. Apple’s Ultra 3 announcement
